​FRIEDRICHSRUH, a village in the Prussian province of Schleswig-Holstein, 15 m. S.E. of Hamburg, with a station on the main line of railway to Berlin. It gives its name to the famous country seat of the Bismarck family. The house is a plain unpretentious structure, but the park and estate, forming a portion of the famous Sachsenwald, are attractive. Close by, on a knoll, the Schneckenberg, stands the mausoleum in which the remains of Prince Otto von Bismarck were entombed on the 16th of March 1899.
